// MAIN //

/**
* Copies elements from an input strided DataView to elements in an output strided array.
*
* @param {NonNegativeInteger} N - number of indexed elements
* @param {DataView} view - output DataView
* @param {integer} strideView - `view` stride length (in bytes)
* @param {Collection} out - input array
* @param {integer} strideOut - `out` stride length
* @param {boolean} littleEndian - boolean indicating whether the data is stored in little-endian format
* @returns {Collection} output array
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
* var DataView = require( '@stdlib/array/dataview' );
*
* var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0 ] );
* var view = new DataView( x.buffer );
*
* var y = new Float64Array( x.length );
* var out = readDataView( x.length, view, 8, y, 1, true );
* // e.g., returns <Float64Array>[ 1.0, 2.0, 3.0, 4.0 ]
*
* var bool = ( out === y );
* // returns true
